Please help. Hello everyone, please help me out. I urgently need to enable secure boot on my Allwinner H3 Nanopi neo core. I tried following the instructions from the forum https://forum.armbian.com/topic/3033-h3-soc-boot-rom-security-e-fuse/#findComment-84051 . But I couldn't burn the E-Fuse. At stage 5, when loading ./sunxi-fel -v -p write 0x2000 of the compiled code and checking whether the changes were applied, sunxi-fel sid/list/version doesn't work. I have to reboot the board, and then I see no result. Please help me solve this problem and burn it so that the bootloader signature is present and it is impossible to boot from the SD card using third-party means. Please, if you have any information, help me.
